WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 231,649, dated August31, 1880,

Application filed July 12, 1880. (No model.)

To all whom it may concern:

Be it known that we, ALLEN M. BURRELL, ALPHONSO R. MINER, and J. W.Bones, of .Oanisteo, in the county of Steuben and State of New York,have invented certain new and useful Improvements in Window-Screens; andwe do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it pertains to make and use it, reference being had to theaccompanying drawings, which form part of this specification.

Our invention relates to an improvementin window-screens; and itconsists in attaching the roller, around which the screen is wrapped orunwrapped as the window-sash is lowered or raised by means of suitablebrackets or hearings, to the lower end of the sash, and then connectingto each end of this roller a wire or cord which has its upper endattached to a tension-spring, as will be more fully describedhereinafter.

The object of our invention is to attach a screen to one or bothwindow-sashes, so that as the sashes are raised or lowered the screenwill be made to cover the openings for the purpose of keeping out fliesand insects of all kinds.

Figure l is a front elevation of our invention. Fig. 2 is a verticalsection of the same.

A represents a window-frame, and B B the sashes. Secured to the lowerend of the lower sash are the two brackets O, of any desired shape orconstruction, and in which the roller D is journaled. Secured to thisroller is the upper end of the screen F, which screen has its lower endsecurely fastened to the windowframe in any suitable manner. This screenmay be made of mosquito-bar, wire-netting, or any othersuitable-material, and is of sufticient width to nicely cover theopening which is made by raising the sash for the purposeof keeping outflies, mosquitoes, and insects of all kinds. A

Each end of the roller is provided with a suitable pulley, around whichis wrapped the lower end of a wire, cord, or chain, G, the upper ends ofwhich wires, cords, or chains are attached to the tension-springs I,which are fastened inside of the upper part of the frame. As the sash ismoved upward the wires G are wound upon each end of the roller at thesame time that the screen is unwound. As the sash is lowered the wirescause the roller to revolve, and thus roll up the screen. It the sash isbeing raised, the screen is unrolled, so as to cover the entire openingthat has been made by the sash, and as the sash is lowered. the screenis wrapped around the roller, so as to be entirely out of the way.

Fastened to the inside lower end of the sash is a suitable board orprotector, O, of any suitable material, which projects over the top ofthe roller so as to prevent any dirt, dust, or other substance fromgetting inbetween the screen, as it is wrapped upon the roller, and thesash. As the sash is being lowered the springs are stretched as thewires, cords, or chains are wrapped upon the roller, and this tension,as the sash is being raised, serves to assist in raising the sashupward. By the use of these springs all necessity for guidingcords,which extend from top to bottom of the frame and are wrapped around theroller, is done away with.

We are aware that a single coiled spring has been used in connectionwith the roller of a window-screen, and this we disclaim. In our screenthe roller is journaled in brackets that are secured to theinside ot'the lower end of the sash, so that the roller is carried up and downwith the sash, and causes the wires G to wrap and unwrap upon the rollerat each end.

Having thus described our invention, we claim- In a window-screen, thecombination of the lower sash, B, the two brackets O, secured to saidsash, roller D, the two cords or wires G, which wrap around the two endsof the roller at their lower ends, and the springs I, substantially asshown.

In testimony that we claim the foregoing we have hereunto set our handsthis 5th day of July, 1880.
